US EVA 90 - NET Feb 2024 (O’Hara and Mogensen)
« on: 10/03/2023 05:26 pm »
MEDIA ADVISORY: M23-126

NASA Sets Coverage of Spacewalks, News Conference for Station Upgrades

Two upcoming spacewalks outside the International Space Station to conduct science research and station maintenance will feature NASA astronauts, both first-time spacewalkers.

NASA astronaut Loral O’Hara will participate in spacewalks on Thursday, Oct. 12, and Friday, Oct. 20, with ESA (European Space Agency) astronaut Andreas Mogensen joining her on the first, and NASA astronaut Jasmin Moghbeli joining her on the second.

Agency experts will preview the spacewalks during a news conference at 1 p.m. EDT on Friday, Oct. 6, from NASA’s Johnson Space Center in Houston.
Live coverage of the news conference and spacewalks will air on NASA Television, the NASA app, and the agency’s website.

News conference participants are:
•       Dana Weigel, deputy manager, International Space Station Program, NASA Johnson
•       Elias Myrmo, spacewalk flight director, NASA Johnson
•       Faruq Sabur, U.S. spacewalk 89 officer, NASA Johnson
•       Sandra Fletcher, U.S. spacewalk 90 officer, NASA Johnson

Media interested in participating in person or by phone must contact the Johnson newsroom no later than 10 a.m., Friday, Oct. 6, by calling 281-483-5111 or emailing [email protected]. To ask questions by phone, reporters must dial into the news conference no later than 15 minutes prior to the start of the call. Questions may also be submitted on social media using #AskNASA.

The first spacewalk is scheduled to begin at 10 a.m. and last about six hours with NASA TV coverage beginning at 8:30 a.m.

On Oct. 12, O’Hara and Mogensen will exit the station’s Quest airlock to collect samples for analysis to see whether microorganisms may exist on the exterior of the orbital complex. They also will replace a high-definition camera on the port truss of the station and conduct other maintenance work to prepare for future spacewalks.

O’Hara will serve as extravehicular activity (EVA) crew member 1 and will wear a suit with red stripes. Mogensen will serve as extravehicular crew member 2 and will wear an unmarked suit. U.S. spacewalk 89 will be the first spacewalk for both crew members.

On Oct. 20, O’Hara and Moghbeli will complete the removal of a faulty electronics box, called a Radio Frequency Group, from a communications antenna on the starboard truss of the station and replace one of twelve Trundle Bearing Assemblies on the port truss Solar Alpha Rotary Joint. The bearings enable the station’s solar arrays to rotate properly to track the sun as the station orbits the Earth. During this spacewalk, Moghbeli will serve as EVA crew member 1 and O’Hara will serve as EVA crew member 2. U.S. spacewalk 90 will be the first spacewalk for Moghbeli and second for O’Hara.

The second spacewalk will begin at 7:30 a.m. and last approximately six and a half hours with NASA TV coverage beginning at 6 a.m.

Was surprised to see that Jasmin Moghbeli was selected as EV-1 on her first EVA, especially with an EVA experienced mate.

Might be more specific training for Moghbeli for the second upcoming EVA. While O'Hare might have more specific training for the first upcoming EVA.

I seem to recall hearing that unless the EVAs are particularly complex (e.g. the AMS-2 repair by Parmitano/Morgan), the EV1/EV2 roles are pretty much interchangeable nowadays.

It's not like the Shuttle era. I think the key difference for EV1 is that they are the one who opens and shuts the airlock hatch. That may be an oversimplification, but that's my understanding.

Spacewalks Postponed as Managers Review Leak Data

NASA engineering and flight control teams are continuing to review data and video associated with a coolant leak from a backup radiator on the station’s Nauka multipurpose laboratory module (MLM). Two United States segment spacewalks originally scheduled for Thursday, Oct.12, and Friday, Oct. 20, have been postponed until the review is complete. New dates will be announced later.

The leak has now ceased, as was reported by Roscosmos flight controllers and evidenced by NASA external station camera views, which show only residual coolant droplets.

The primary radiator on Nauka continues to work normally, providing full cooling to the module with no impacts to the crew or to space station operations.

The backup radiator was delivered to the space station on the Rassvet module during space shuttle mission STS-132 in 2010. It was transferred to the Nauka during a Roscosmos spacewalk in April.

Teams on the ground continue to investigate the cause of the leak, and additional updates will be made as soon as available.

Spacewalks Rescheduled as NASA Reviews Leak Data
NASA astronaut Loral O'Hara is pictured trying on her spacesuit and testing its components aboard the International Space Station ahead of an upcoming spacewalk.

Two United States operating segment spacewalks outside the International Space Station have been rescheduled for no earlier than Thursday, Oct. 19, and Monday, Oct. 30, as a result of ongoing review by NASA managers and engineers after a coolant leak from a backup radiator on the station’s Nauka multipurpose laboratory module.

The spacewalks were deferred from their original target dates to allow engineers additional time to complete their analysis of the coolant leak, which occurred on Oct. 9 and has now stopped.

During the first spacewalk NASA astronaut Loral O’Hara and ESA (European Space Agency) astronaut Andreas Mogensen will exit the station’s Quest airlock to collect samples for analysis to see whether microorganisms may exist on the exterior of the orbital complex. They also will replace a high-definition camera on the port truss of the station and conduct other maintenance work to prepare for future spacewalks.

O’Hara will serve as extravehicular activity (EVA) crew member 1 and will wear a suit with red stripes. Mogensen will serve as extravehicular crew member 2 and will wear an unmarked suit. U.S. Spacewalk 89 will be the first spacewalk for both crew members.

During the second spacewalk, O’Hara and Jasmin Moghbeli will complete the removal of a faulty electronics box, called a Radio Frequency Group, from a communications antenna bracket and replace one of twelve Trundle Bearing Assemblies on the port truss Solar Alpha Rotary Joint. The bearings enable the station’s solar arrays to rotate properly to track the sun as the station orbits the Earth. During this spacewalk, Moghbeli will serve as EVA crew member 1 and O’Hara will serve as EVA crew member 2. U.S. Spacewalk 90 will be the first spacewalk for Moghbeli and second for O’Hara.

Details on times for the spacewalks are being reviewed and times for live coverage on NASA Television, the agency’s website and the NASA app and will be shared once available.

EVA 90 now NET December 2023:

Quote
O’Hara and Mogensen had been planning to conduct a spacewalk this month to collect samples and examine the possibility of microbes living on the outside of the orbital laboratory. However, mission managers have decided to defer that spacewalk to no earlier than December as they review data from a backup radiator leak that has since ceased.

EVA Sample Kit Fun Facts

Up to eight microbial samples can be taken per EVA excursion with one kit. Only one tool handle is needed for all 8 samples.

The tool handle is a heritage Space Shuttle tile repair device designed to quickly snap into different attachments by means of a spring-loaded mechanism that engages a mating device in each end effector

Items deferred from the original EVA-90 plan to accommodate the RFG retrieval:

 - High-definition camera replacement on CP9 (Mogensen)
 - DDCU jumper installation on the P4 IEA (O'Hara)
 - AMS-related tasks testing access for future installation of Layer 0 (both)

If O'Hara and Mogensen carry out this EVA, the timing is tight between the departure of Ax-3 at the beginning of February and the arrival of the Crew-8 in mid-February.

What is happening with the SSRMS Elbow joint?

The posted steps suggest that it's not the joint currently on the SSRMS that's involved, but rather the spare SSRMS Pitch/Roll Joint currently on ESP-2 - something about reconfiguring some of the Expandable Diameter Fasteners that are used to connect the SSRMS components, and also manually moving the angle of the joint. That particular joint was launched to the station on STS-118 back in August 2007, and I don't believe it's been manipulated since.

Correct, all ops on the spare (likely to verify that things are still functioning smoothly / correctly)

According to Rob Navias, this EVA will no longer occur during Exp70, due to busy schedule at ISS in Feb. It will take place later this year.

Any updates on EVA 90?

There was a tweet from Andreas Mogensen that mentioned its cancellation / deferral:

Unfortunately the spacewalk I was planned to go out on will not be performed this time, but maybe in the future by another crew.
